Don't get too misty eyed about flying airlines for an entire career. It is not an intellectually demanding job per se even though it requires an element of dedication and enthusiasm to jump through the various hoops to reach the final goal. Unless daddy pays ( ever more common ) it requires considerable financial investment with no guarantee of a job at the end of training; rather like getting a degree with consequent large student loan. Terms and conditions of service are continually under threat ( BA today ) and the halcyon days of the fifties and sixties are long long gone. There are some great people in the airline business and there is satisfaction to be gained but think long and hard about the prospect of forty years plus in an ever more automated world.
You must make your own choices but the prospect of a good degree from a good university would allow you some time to reflect on your options before joining the airline treadmill. There are of course other options flying aircraft at the Queens expense which could still lead to the airlines at a later date. Incidentally, whilst some degree courses these days are a bit of a joke, don't get misled by those who quote the need to study an aviation related subject such as engineering. To be a pilot it is simply not necessary to have a scientific based degree, there are plenty of good pilots with degrees in the Arts, the Law and many other subjects with no aviation connection. Always better to study a subject you enjoy.
Good luck
